Yes, it is allowed, you can ask any questions concerning MT4 and MT5

Hi everybody.


I'm learnin new MT4 coding. But I know metastock very well.

I want to draw diffarent a moving average for examination and learning code writing menthality.


For example (Metastock version)

M1= Close;

M2=MOV(M1,5,S); // Simple 5 period moving average of M1

M3=MOV(M2,5,S); // Simple 5 period moving average of M2


I've wrote above code on MT4 but not working. How can i write this code on MT4 ?


Can anybody help me??


Thanks for your advice.

    Look at the URL of the up arrow it is https://www.mql5.com/en/forum/mql4 Which is the MQL4 section, (bottom of the Root page.) Either you posted in the correct location, or more likely a moderator has already moved it.
              General rules and best pratices of the Forum. - General - MQL5 programming forum

    And edited hsaglam's broken code using SRC.

  2. "Doesn't work" is meaningless - just like saying the car doesn't work. Doesn't start, won't go in gear, no electrical, missing the key, flat tires - meaningless. There are no mind readers here and our crystal balls are cracked. You must provide information.

  3. Buf_1[i]=iMA(NULL,0,5,0,MODE_SMA,Buf_0[i],i);
    The second from the last argument must be ENUM_APPLIED_PRICE
              iMA - Technical Indicators - MQL4 Reference

    What you are trying to do, requires iMAOnArray

  4. int start()                         // Special function start()
:
   Counted_bars=IndicatorCounted(); // Number of counted bars

Hi.

First my english is not good. I'm sorry for this.

And thanks for your helpfull advice.

I want to draw a moving average on chart window like above graphic.

I'll try loopbacks methods and iMAOnArray function.

Use the "SendNotification()" to send out Push Notifications to the app. but remember to setup the app's "MetaQuotes ID" in the settings of the desktop MT4 terminal application, for it to work!

Hello everybody. I am new in mql4 programming. How can I attach two objects together as the they move at the same time. I mean when I move object1 by mouse, I need the object2 to follow the direction of object1. I have the following code and it works good, but there are two problems:

1. As my timer function works permanently, the memory or CPU is working too much.

2. There is a tiny lag between movement of object1 and object2 that does not look like pretty (it moves with a kind of vibration). I tried to solve it by changing in timer speed, but the result was not good. I am looking for code to attach two objects perfectly.

For example descriptions on Fibonacci levels (i.e., 61.8%) move perfectly when I move my Fibonacci retracement. I'm looking for an attachment like that.

Thank you
